Embodiment Construction

[0025] In view of this, the core of the present invention is to disclose a method for detecting the diameter of steel bars in concrete members, which can reduce the damage to the bearing capacity of members while obtaining the diameter of steel bars.

[0026] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the invention discloses a method for detecting the diameter of steel bars in concrete members, which comprises the following steps:

[0028] Step S1: Drill inspection holes.

[0029] Drill the inspection hole along the axial direction of the steel bar of the concrete component to be tested, and ensure that the depth of the inspection hole reaches the surface of the steel bar. Specifically, use a percussion drill to drill the hole. After the drilling ...

Abstract

The invention discloses a method for detecting the steel bar diameter in a concrete member. The method comprises the steps that a detection hole is drilled in the axial direction of the steel bar of ato-be-detected concrete member, and the depth of the detection hole reaches the surface of the steel bar; the resistance and the distance between any two detection holes are detected, and according to the formula R=rho*L\ S, rho is the resistivity of the steel bar of the to-be-detected concrete member, L is the length of the steel bar of the to-be-detected concrete member, and S is the sectionalarea of the steel bar of the to-be-detected concrete member; the sectional area of the steel bar of the to-be-detected concrete member is obtained, and the diameter of the steel bar is calculated andobtained. Only three or other numbers of holes need to be drilled in the member, the depth of the hole is only the thickness of the steel bar protection layer, the steel bar cannot be damaged, and therefore the influence on the bearing capacity of the to-be-detected concrete member can be ignored.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for detecting the diameter of steel bars in concrete components. Background technique [0002] When renovating or evaluating existing concrete buildings, it is necessary to find out the configuration of steel bars in the concrete components to calculate the bearing capacity of the components. However, many existing buildings were built too early and the drawings were not properly preserved, so it is impossible to find out the configuration of the steel bars through the drawings. [0003] Existing methods for detecting the diameter of steel bars in concrete members usually use the chisel method. The chiseling method is to chisel out the steel bar from the concrete and measure the diameter directly with a caliper. Specifically, it is necessary to chisel out a large hole on the surface of the component to expose more than half of the cross-section of a steel bar...
